He definitely isn't a flash in the pan, if I need to explain why then you don't know anything about Adrian Gonzalez, lol. (and therefore shouldn't be commenting on him)

I'm not saying Gonzalez won't become a valuable player eventually. But obviously the power he showed wasn't sustainable as his previous minor league numbers concur with. I know that. He's a Mark Grace type. Great average with 25 HR max power.
